Abstract

The repair link is a C-shaped member and a junction member, the junction member having enlarged tongues with narrower roots and the C shaped member is complementary. Welding to hold the junction member in place preferably is caused to adhere to the C-shaped member rather than the junction member.

Claims

1. Junction link comprising:

a C-shaped member and a junction member having two free ends,

the C-shaped member defining generally mutually facing free ends,

the junction member being designed to provide surfaces which complement said C-shaped member and to form therewith a complete ring, in an assembled position said ring generally defining a plane,

said junction member and said C-shaped member being designed to slide into assembled position in a direction generally perpendicular to the plane of the ring,

said junction member defining at each free end, enlarged tongues having narrow roots and a thicker body and shaped to slide in said direction relative to said body,

complementary groove-shaped members in said C-shaped members adapted to receive said tongues,

means adapted, when said members are in assembled position, for preventing movement of said members out of assembled position,

wherein said junction member is shaped to define a pair of recesses facing, in assembled position, the respective free end faces of said C-shaped member and wherein welding material is provided in said recesses adhering to said free ends.

2. Junction link as claimed in claim 1 wherein said tongues, outwardly of said roots are provided with a circular section.

3. Junction link as claimed in claim 2 wherein the ring defined by said C-shaped member and said junction member defines a circle when viewed in the direction perpendicular to the plane of the link.

4. Junction link as claimed in claim 1 wherein the ring defined by said C-shaped member and said junction member defines a circle when viewed in the direction perpendicular to said plane of the link.

5. Method of forming a junction link including the steps of:

providing a C-shaped member defining generally mutually facing free ends,

providing a junction member having two free ends designed to provide surfaces which complement said C-shaped member and in assembled position form therewith a complete ring, said ring defining the median plane,

where said junction member and said C-shaped member are designed to slide into assembled position in a direction generally perpendicular to said median plane,

where said junction member defines a pair of recesses which in the assembled position face the respective free ends of the junction member,

providing on the surfaces of said junction member which define said recesses, a heat resistant insulating coating sliding said junction member into assembled position with said C-shaped member,

with arc welding at least partially filling said recess with welding material primarily welded to said free ends.

6. Method of forming a junction link including the steps of:

providing a C-shaped member defining generally mutually facing free ends,

providing a junction member having two free ends designed to provide surfaces which complement said C-shaped member and in assembled position form therewith a complete ring, said ring defining a median plane,

where said junction member and said C-shaped member are designed to slide into assembled position in a direction generally perpendicular to said median plane,

wherein said junction member has surfaces defining a pair of recesses which in the assembled position face the respective free ends of the junction member, sliding said junction member into assembled position with said C-shaped member,

with arc welding, attaching welding material to said free ends within said recesses while inhibiting attachment of material to the surface defining said recess.
